Honestly, the first one did not work. It would run for a couple of seconds and then give a code like it was jammed. A phone call to customer service was short and sweet, I was told some of the early models had this issue and they would send me a replacement. Included with the new one was a label to return the defective unit. We brew a lot of coffee for ourselves and guests. The old grinder sounded like a turbo jet taking off. The Kitchenaid gives a very uniform grind for our Bunn pour over maker. It just took a couple of adjustments to get the perfect amount. Now there are no worries about waking anyone up when I make a pot early and we don’t have to stop a conversation while grinding. I cannot imagine there is a grinder that offers any better grind or quieter operation. The excellent customer service was icing on the cake.
